The Technology Defined
Radar stands for "Radio Detection and
Ranging" – utilizing radio frequency
waves to detect targets. At its core,
radar is an object detection sensor
using radio waves to determine the
range, altitude, direction and speed of
objects. "is means radar can detect
anything from an aircra approach-
ing an airport terminal to a human
approaching a power plant fence line,"
Zussman says. "Ground-based radar
solutions provide 24/7, 360-degree
coverage of any protected site,
allowing for cost-effective, volumet-
ric perimeter protection in all weather
and lighting conditions."
LiDAR (light imaging, detection,
and ranging) uses pulsed laser light
to measure distances in a similar way.
"LiDAR bounces out laser beams, mea-
sures how long it takes for the light to
hit an object or surface, calculating the
distance to the object the light just hit
and forming data points," Surfaro says.
"Millions of those data points, called
'point clouds' are processed as a 3D
visualization in seconds, rendering accu-
rate object displays – all without video
surveillance cameras. Unlike radar or
sound waves, LiDAR does not dissipate
as it travels back to its scanner."

depressions (grades), rendered in an illustration colorizing objects according to
their height.
